Photoluminescence of [Pt(C3Ph3)Ln]PF6 with L=phenylphosphine ligands. Emission from a (Pt0 to C3Ph3+) MLCT triplet

Abstract

The complex cations [Pt-0(C3Ph3)(PPh3)(2)](+) and [Pt-0(C3Ph3)(tripod)](+) with tripod = CH3C(CH2PPh2)(3) contain the smallest Huckel aromat C3R3+ (with n = 0) as ligand. Since this cation is a CT acceptor, the complexes are characterized by low-energy (Pt-0 to C3Ph3+) MLCT states. The complexes show a photoluminescence which originates from the lowest MLCT triplet.
